First time here but I have a question regarding my speakers and onboard audio. I went out and bought the Z-5300's and hooked em up, however one speaker doesnt work. The problem lies in my onboard audio, i hooked it up to 5.1 and it works. However i realized awhile ago that the green input in the back(onboard) was always finiky. Sometimes it wouldnt want to cooperate with me when i pluged something into it(ie not play, scratchy). So i started using the front connection.(side of my computer, another green input/pink mic). This worked wonderfully for my last speakers. However now that i need 3 inputs, i dont have another connection on the front of my case for this, only 2 like stated above. When i try to use the 2 in the back, and use the Green input on the front, my mobo disables the sound in the rear inputs, and only allows anything pluged into the front to work. Sooo running a longer cord to the front(green input), allows my 2 front speakers to work, but disables my sub/center and rear speakers. Is there a way to disable this feature, so that anything plugged in anywhere will run? (2 in back, 1 in front) I really dont want to have to buy a sound card quite yet. Thanks, Cupcakke.
